The SiaCoin team has confirmed there is a bug in the wallet and that they are working on a patch. Deposits and withdrawals will remain disabled until this patch is implemented and tested.
I have same problem with Poloniex. Over 2500 SC lost!!
What is Sia team doing to fix this?
I am having the same issue. Does the Sia Team even know about the issue? If not, how can we report it to them?
